Solvent extraction plant SPARES manufacture in India
High-quality, durable solvent extraction plant spare parts and replacement equipment for Solvent Extraction and Edible Oil Refinery plants manufactured in house at Dhuri, Punjab by Super Techno Engineers Private Limited.
Solvent Extraction Plant Spares
Super Techno Engineers is a trusted solvent extraction plant spares manufacturer and oil extraction machinery supplier serving oil processors across India, Tanzania, and Zambia. Every spare and equipment we manufacture is precision fabricated in our own facility using high grade carbon steel and stainless steel, ensuring dimensional accuracy, long service life, and seamless compatibility with both new and existing solvent extraction plant installations.
Desolventization Toaster (DT)
Super Techno Engineers manufactures complete Desolventization Toaster systems and DT spare parts for solvent extraction plants of all capacities. The Desolventizer Toaster removes residual hexane solvent from extracted oilseed meal by applying jacketed and open steam across multiple compartments. The wet solvent loaded meal enters the DT, steam is applied causing hexane to evaporate, and the meal is simultaneously toasted under controlled moisture and temperature conditions to deactivate anti nutritional enzymes. The final output is high protein desolventized toasted meal suitable for poultry, animal, and fish feed applications. Solvent vapors released during the process are recovered and recirculated back into the hexane recovery system, ensuring minimal solvent loss across the entire extraction circuit.
Solvent Extractor Assembly
The Solvent Extractor is the core equipment in any solvent extraction plant and the heart of the entire oil recovery process. Super Techno Engineers manufactures complete solvent extractor assemblies for continuous moving bed extraction systems. Prepared oilseeds, expelled cakes, or expanded materials are fed into the extractor through a sealed rotary valve feeding system. Inside the extractor, hexane solvent is sprayed counter currently over the moving bed of material, dissolving the oil to form miscella. The miscella is collected, filtered, and transferred to the miscella holding tank, while the de oiled meal is conveyed through a sealed system to the Desolventizer Toaster. Our solvent extractor assembly includes the extractor body, Redler chain, Bulk flow chain, Elevator chain, Solvent Extractor chain, wedge wire screens, drive mechanism, and all associated structural components all manufactured and supplied as complete assemblies or individual replacement parts.
Batch Extractor
Super Techno Engineers manufactures Batch Extractors for small to medium scale solvent extraction plant operations where oil is extracted from oilseeds in fixed cycles rather than continuously. The prepared seeds are loaded into the batch extractor, hexane solvent is added to dissolve the oil content, and after the specified retention time the miscella is drained and the de oiled meal is discharged. The process is repeated for each batch. Our batch extractors offer precise control over temperature and solvent ratios, making them ideal for specialty oilseed processing, pilot plant operations, and processors requiring flexible production scheduling. Complete batch extractor units and individual Solvent Die plates and internal components are available for supply and replacement.
Solvent Condensers
Super Techno Engineers manufactures Solvent Condensers for hexane vapor recovery in solvent extraction plants. Solvent vapors generated from the extractor, desolventizer toaster, and evaporators are directed to the condensers where they are cooled using cooling water or chilled water, converting hexane vapors back into liquid solvent for reuse. Our condenser systems are designed for maximum heat transfer efficiency, minimum hexane loss, and long service life under continuous operating conditions. We supply complete condenser units as well as replacement condenser components for all major solvent extraction plant configurations.
Economizer
Super Techno Engineers manufactures Economizers for heat recovery in solvent extraction plants and edible oil refinery systems. The Economizer captures thermal energy from hot outgoing fluids including vapors and exhaust gases and transfers it to incoming process streams such as miscella, oil, water, or solvent. This waste heat recovery process significantly reduces steam consumption, lowers fuel costs, and improves the overall thermal efficiency of the complete oil processing plant. Our economizers are fabricated from high grade materials and are available as complete units and as solvent extraction plant maintenance parts for existing installations.
Solvent Heaters
Super Techno Engineers manufactures Solvent Heaters used in the miscella distillation and solvent recovery circuits of solvent extraction plants. Solvent heaters raise the temperature of miscella and process streams to the required levels for evaporation, distillation, and solvent stripping stages. Our solvent heaters are shell and tube type, fabricated from carbon steel or stainless steel depending on the process fluid, and are available as complete heater units or as replacement components for existing miscella distillation systems.
Miscella Pump
Super Techno Engineers supplies miscella pumps for solvent extraction plants, designed specifically for handling hexane and oil miscella mixtures under the operating conditions of the extraction and distillation circuits. Our miscella pumps are built for continuous duty, corrosion resistance, and leak proof performance, ensuring reliable miscella transfer from the extractor to the holding tank and through the evaporator stages without hexane vapor losses.
Rotary Valve
Super Techno Engineers manufactures rotary valves for solvent extraction plants used as sealed material feed devices at the extractor inlet. The rotary valve controls the flow of prepared oilseeds, cakes, or flakes into the sealed extraction environment while preventing hexane vapor from escaping into the surrounding area. Our rotary valves are precision fabricated for airtight sealing, adjustable throughput, and long service life under continuous solvent plant operating conditions.
Technical Queries
Frequently Asked Questions
Engineers uses high grade carbon steel for structural and mechanical components including the extractor body, DT trays, and conveyor systems, and SS 304 and SS 316 stainless steel for components in direct contact with edible oil, miscella, and food grade process streams. All materials are selected to meet IS and international standards for solvent extraction plant and edible oil refinery applications.
solvent extraction plant spares and equipment are designed for universal compatibility with all major plant configurations. We customize dimensions, flange ratings, and material specifications to match your existing plant layout, ensuring seamless integration without major structural modifications. Send us your existing drawings or equipment specifications and our engineering team will confirm fit and supply.
Lead time depends on the equipment type, size, and technical specifications. Standard spare parts including Redler chains, Bulk flow chains, Elevator chains, Solvent Extractor chains, and Solvent Die plates are typically ready within 2 to 4 weeks. Complete equipment assemblies such as Desolventization Toasters, Solvent Extractor assemblies, Solvent Condensers, and Economizers typically take 4 to 8 weeks from order confirmation at our Dhuri, Punjab manufacturing facility.
The Economizer recovers waste heat from hot outgoing vapors and exhaust streams and transfers it to incoming process fluids including miscella, water, and solvent. This preheating reduces the amount of fresh steam required at each heating stage, directly cutting fuel and steam consumption across the entire solvent extraction plant. Well maintained economizers typically deliver measurable reductions in utility costs per ton of oilseed processed.
